IMPROVEMENT lN MACHINES FOR SAMPLING ORES AND OTHER MATERIALS.

Specification forming art of Letters Patent No. 146,167; dated January 6, 1874 application filed July 19, 1873.

To all whom it may concern:

Be it known that I, J OHN CoLnoM, of Idaho Springs, in the county of Clear Creek and Territory of Colorado, have invented a new and Improved SamplingMachine, of which the t'oL lowing is a specification:

My invention consists of a small short spout, which is slowly and regularly moved at intervals under the mouth of a spout-or trough, through which the substance to be sampled is caused to run, and receives a certain portion of the said substance, and diverts it from the regular course into a sample-box. The proportion of the substance taken to the whole mass is determined by the proportion which the said short spout or receiver bears to the length of the circuit it travels, in the greater portion of which it is not passing the spout. The object is to obtain from crushed ore, grain, and other substances, samples representing an average as to quality, and the proportionate weight.

Figure l is a plan view of 1n y improved sampling-machine, with a part broken out to show the parts below more distinctly. Fig. 2 is a longitudinal sectional elevation taken on the line a: w of Fig. 1.

Similar letters of reference indicate corresponding parts.

A is the spout through which the substance to be sampled, say crushed ore, is to be carried, and discharged, at the mouth B, into another spout, G, to conduct it away again. 1)

is the short samplingspout or receiver for moving past the mouth B, to receive a small portion while passing, and divert it to the sample-box E, through the spout F. This sampling spout or receiver is mounted on the it travels determines the proportion taken of s i the substance to be sampled.

When crushed ore is to be sampled, it will be run with water through a comparatively fiat spout, but for grain, sand, and other dry substances, the descent will be steeper.

Having thus described myinvention,I claim as new and desire to secure by Letters Patent The combination of the sampling spout or receiver D with a conducting-spout, A, when provided with a revolving shaft and arm, and arranged in a predetermined proportion to its circuit, and also arranged for diverting the substance received by it from the conductin spout from the regular course into a samplereceiver, substantially as specified.

JOHN OOLLOM.
